I find that I'm having the same problem as the previous person to comment. It keeps asking me to click on an activity for practice, however I've already gone through them all. I don't find that the system is very easy to use.
The sound wouldn't come on so I couldn't hear til the very end.
Also on the first video for the New orientation it kept asking to click on activity then practice to try various practice but it was the same one and I just kept clicking on yellow folders to go through them tried once to use back arrow button and then had to start over.
